If you've ever battled a crusty, white-tinged patch in your yard where nothing grows, this research pinpoints exactly how adding manure compost rebuilds the soil chemistry that salt destroys.
Salty soil is a real problem: it stops plants from drinking water properly and wrecks the soil's structure. Researchers tested sheep manure compost and organic fertilizer on saline soil, then used a laser-based scanning technique paired with AI to see precisely which chemical changes made the dirt healthier again. The manure compost came out ahead, reliably boosting organic carbon and fixing the sodium imbalance that makes salty soil so hostile to roots.
Key Findings
Sheep manure compost outperformed organic fertilizer, with prediction accuracy (R2) between 0.96 and 0.98 for key soil properties like sodium content, organic carbon, and dielectric constant.
A deep learning model (1D-CNN) beat older statistical methods, reaching near-perfect accuracy (R2 > 0.99) for predicting soil sodium levels and electrical properties from infrared scans.
PCA analysis showed amended soils clustered distinctly apart from untreated saline soil, confirming a clear compositional shift toward healthier, more productive conditions.

Scientists used infrared light scanning and AI to figure out exactly how sheep manure compost and organic fertilizer fix salty soil, tracking changes down to the molecular level with over 95% accuracy.

Enhancing saline soil quality using enriched sheep manure compost and organic fertilizer: A FTIR-Deep learning evaluation of physiochemical and electrical properties.
Soil salinity restricts nutrient uptake, degrades soil structure, and ultimately reduces crop productivity. In this study, electrical, physical, and chemical soil properties were measured using sta...

Composting is the controlled decomposition of organic materials—such as plant waste, food scraps, and manure—into a nutrient-rich amendment that improves soil fertility and structure. For plant science, compost is significant because it enhances soil microbial communities, increases nutrient
